We derive the quartic interaction vertex of pure Yang-Mills theory bydemanding closure of the light-cone Poincar\'e algebra in four-dimensionalMinkowski spacetime. This calculation explicitly shows why structure constantsmust satisfy the Jacobi identity. We then prove that corrections to the spingenerator, for spin one at this order, vanish. We comment briefly on higherspin fields in this context.
